Look closely at the bottom of the tank. My 761 had a Fram and Hastings number stamped in it. Don't remember if it was inside or outside. It's all waxed up and sealed now after chroming. I have the old filter if you need measurements.

Thanks for the reply Paul. I went and looked all over the thing again alas no numbers. If your filter housing looks like this one yes i would very much like to know the number off the old filter

Same housing, this should be it. Exact same dimensions as my old filter. There's even a Brockway part number for it!

No problem, you're welcome. Not sure if you know this, Stan said this is the oil that goes in the power steering. I got it at Tractor Supply.... The only place I found it. All my regular suppliers were special order.... $$$$$$$$

That's correct for Sheppard power steering, 20W non-detergent oil.

Question???
And I know I talked with Stan on this once before, but the oil spec in the manual is different??

So Why the 20W oil??

I know that most Brockways use a 92 series box.

Not sure of the date on the above service bulletin, but initially when Brockway started using the Sheppard unit, their spec was for the 20W. It may have changed as the bulletin describes in later years. I have found that the 20W out performs ANY other oil. ATF is too thin at operating temperature, you loose assist and it is prone to leaks. The multi-weight oils tend to make the unit very sluggish and it also seems to foam and then will build pressure in the reservoir. Another factor to consider, is the Vickers hydraulic pump that is used to supply pressure for the Sheppard box. It is designed to be used with 20W hydraulic oil. The only major difference between 20W ND motor oil and 20W hydraulic oil is the additives for use in a combustion engine in the motor oil. Why didn't Sheppard/Vickers/Brockway spec hydraulic oil ? GOOD QUESTION !!! The best advice I can give, from my personal experience, is use the 20W non-detergent motor oil. It will work.

Maybe I can shed a little light on this. Conventional 10w40 oil's were sludge prone over other oil weights. Recently many auto makers list 10w40 oil as specifically not recommended in the owners manuals. In the 70's and early 80's it was a very popular grade. 10w40 viscosity index improvers caused the oil to sludge by means of oxidation. The viscosity index improvers were simply paraffin (wax)... Up to 1/3 by volume. Keep in mind this is not a lubricant! This was the cause of sludge and foaming. Remember the small block Chevy camshaft failures? Even pulling a valve cover off one of those things tells the full story. Since the service bulletin was probably written during that era, it's not surprising they recommended 10w-40.... The oil companies were telling all the manufacturers it was the "miracle oil", perfect at all temps. Besides that, you really don't need or want detergents in a hydraulic system. Personally I wouldn't use it to lube a door hinge, I've repaired way too many engines with the damage caused by it.

Stan, I remember you telling me this before, it was just recently that I downloaded the manul and ran across the lube specs.
I have been running straight weight in mine since i resealed it two years ago..

I just couldn't remember the reasoning. (Old age brain fart i guess :roll: ) it happens :lol:

Thanks guys.
